- Application filed July 21, 1914. Serial No. 852,173.

To all 'whom it may concern:

Be it known that I, LAWRENCE A. SUBERS, a citizen of the United States,and resident of East Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in a Laminated,Cohesive, Interwound, Bonded Fabric, of which I hereby declare thefollowing to be a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same.

The objects of the invention are to provide a fabric of the typedescribed in Letters Patent granted to Lawrence A. Subers upon March 26,1912, and bearing Number 1,021,014.

This fabric has been described in the aforesaid Letters Patent as alaminated, cohering, interwound fabric, constructed upon a cylindricalmandrel, from series of spirally wound fabric bands, which cross eachother at predetermined angles.

In the previously described fabric, the bands which comprise the fabricportion thereof are first made in tubular form and afterward flattenedand are constructed from series of fibrous elements or flexible memberswhich are coated with a liquid adhesive such as rubber during theprocess of construction of the band.

In my prior Patent No. 1,187,564, a flattened band of the same type asthe preceding is described, in which in addition to the liquid adhesivewith which the fibrous elements are coated during the construction ofthe band, a continuous layer of solid vulcanizable adhesive isinterposed between the fibrous elements.

In this manner the amount of adhesive incorporated in the body of theband is greatly increased, and the fibrous elements in the sides of theflattened band willadhere together more strongly when the additionalamount of adhesive is thus introduced, andwill not readily tear apartwhen the band is placed under tension or strain. ,Also when the bandsare placed under a preliminary tension to control the amount ofsubsequent extensibility thereof, this increased amount of adhesion willprevent any tendency of the bands to resume the tubular form.

To a complete understanding of the fabric the construction of the fabricbands must be understood.

These fabric bands are constructed from a plurality of series ofparallel spaced,'in-

terwound, cohering fibrous elements, one

series crossing the other at a predetermined angle and coated withliquid adhesive. Between the series of fibrous elements is interposed acontinuous layer (which may be bands) of solid, which fills all openingsbetween the fibrous elements and appears upon the surface in regularlypositioned diamond shaped spaces.

From such bands the laminated, cohering, interwound fabric isconstructed, and the exposed diamond shaped portions of the adhesive inthe crossing bands cohere together, thus binding the elements of thefabric more closely together and incorporating in the fabric a greatlyincreased amount of solid adhesive, and producing a bonded fabric whichis possessed of a high resiliency, strength, and durability, and therebygreatly increasing its efiiciency for general use.

This fabric, although a laminated structure, possesses no place ofcleavage after it has been vulcanized, but is bound together into ahomogeneous, unitary mass. The invention is hereinafter furtherdescribed, shown in the accompanying drawings, and specifically pointedout in the claims.

In the accompanying drawings, Figure l is an isometric view showing themanner. of constructing the fabric from series of fabric bands; Fig. 2is a plan view of a tube showing portions of each series of bands brokenaway; Fig. 3 is a plan view of one of the fabric bands showing thediamond shaped spaces formed by the solid adhesive in its surface; Fig.4 is a transverse section of one of the fabric bands, enlarged, andshowing a rubber layer interposed between the yarn elements thereof;Fig. 5 is a similar enlarged section showing an added central band ofrubber or other adhesive inclosed between the sides of the flattenedband; Fig. 6 is a transverse section (enlarged) through line 66 Fig. 2,showing the layers of solid adhesive incorporated in the several fabricbands; Fig. 7 is a similar section showing fabric bands having a centralband of rubber incorporated therein in addition to the other layers ofsolid adhesive; Fig. 8 is a longitudinal section on line 8-8 Fig. 6.

In these drawings A, A, are fabric bands formed originally upon amandrel by wind vulcanizable adhesive,

2. In a laminated fabric, a series of spaced, parallel, cohering andinterwound, laminated, fabric bands, each band composed of series ofparallel, cohering, interwound flexible, fibrous elements, one spacedseries of elements crossing another spaced series of elements at apredetermined angle, providing spaced diamond shaped openingsinterspersed throughout the bands, some of said diamond shaped openingsbeing positioned in the outer surface of each band, and a solid adhesivefilling all said openings, the adhesive filling the said surfaceopenings in one band cohering to the adhesive filling thesurface'openings in adjacent bands and serving as a bond to unite thebands into a unitary structure.

3. In a laminated fabric, a series of spaced, parallel, cohering,interwound, laminated fabric bands, each band composed in turn of crossseries, of spaced, parallel,

- cohering interwound fabric elements, the

elements in each individual band being arranged in layers, and crossingeach other at an angle, and a layer of solid adhe sive materialinterposed between adjacent layers of fibrous elements, said adhesivelayer separating and cushioning'said fibrous elements at crossing pointsand being exposed along the exterior'side of each band in spacedpositions, the solid adhesive upon the exterior sides of adjoining bandscohering in said fabric and serving as a bond to unite said bands into aunitary structure.

4. As an article of manufacture, a laminated fabric comprising-a seriesof laminated, spaced, interwound, fabric bands, each of said bandscomprising spaced, parallel, flexible elements interwound in layers,

the elements in one layer crossing those of another, and in which bandsfluid adhesive is incorporated to cause the fibrous elements 1n saidbands to cohere, said bands having interspersed and surface openingstherein,-

said openings filled with a solid adhesive and said solid adhesive alsoforming a cushfabric bands, each band composed of crossed series ofspaced, parallel, ,coherlng, interwound fibrous elements, between theseveral series of which a layer of solid adhesive material isinterposed, and which is exposed upon the exterior sides thereof inspaced positions, said exposed portions of the adhesive material beingof a thickness substantially equal to the thickness of the surfaceportions of fabric on each side thereof.

6. In a laminated fabric, a series of laminated, cohering, interwoundbands, each band provided with exterior and interspersed openingscontaining solid adhesive of material thickness compared with thethickness of the fabric layers adjacent thereto, the adhesive in theexterior openings in adjoining bands cohering to unite said bands into aunitaryv structure.

In testimony whereof, I hereunto set my hand this eighteenth day'ofJuly, 1914.
